我在Unity上遇到了很多问题，实际上我已经在笔记本电脑上全新安装了Xubuntu。
不幸的是，我的主桌面已通过网络从Ubuntu 10.04升级到11.04，即使我已经启动并运行gnome面板（并尽可能禁用Unity快捷方式），我仍然更喜欢Xubuntu桌面。
有没有一种方法可以从Ubuntu切换到Xubuntu（或从Unity切换到XFCE），而不必进行所有备份/安装/还原工作？
我们可以简单地下载某种类型的软件包来将XFCE安装为窗口管理器吗？
这是否是一个理智的考虑，还是我应该硬着头皮完全重新安装？

如果您需要xubuntu-artworks，普利茅斯主题甚至gdm主题，则也可以安装它们。
